Utmost tensile strength

The nature of the area for dropping the catalyst must be prescribed. The ideal condition is that the area has the same hardness as that of the catalyst it can be harder than that of the catalyst and not softer. For tablets, the minimum drop height for particle fracture is related to the diameter/height ratio and the tablet s utmost tensile strength (UTS). A rough approximation of the relationship is as follows The drop height for particle fracture (m) = 0.075 x d/Lx(UTS), UTS is expressed in kg Cm . ... [Pg.713]

Transition Zone III is of utmost importance, since the formation of dry spots is accompanied by a dramatic change in the heat transfer mechanism. In such units as gas-fired boilers, the dry spots may cause the tube wall temperature to approach the temperature of the heating gas. However, before the tube wall temperature reaches a steady-state value, the tensile strength of the tube wall is reduced, and rupture may occur. This phenomenon, called burn-out, may also occur at any point along the tube wall if the wall heat flux qmt is large enough so that a vapor film forms between the tube wall and the liquid surface. [Pg.41]
